Actually, Java / JEE / Spring is the analogy I use when talking to people about the massive of complexity that is being created in the JavaScript ecosystem at the moment. As you create it, new complexity looks "free" because the creator understands it perfectly (they are creating it!) and their nearest peers understand it too (they have the same immediate problem as the creator!). But it's a one way path - like navigating through a complex maze - going forward is easy and you come out the other size eventually, but nobody will ever be able to retrace those steps. In the longer term the complexity has an enormously high price, and eventually it collapses in on itself - new developers just won't use it. Other ecosystems are complex but not at the same scale as those two IMHO, because different ecosystems seem to put a different price on complexity.
